Passwords leak; two-factor makes leaking insufficient
An account protected only by a password falls completely once that password leaks. A second factor means the attacker also needs your device.
Binance typically supports authenticator apps and SMS, with the app more reliable and SMS best kept as backup.
What to prepare before you start
These five things cover almost every delay people run into: A phone able to install an authenticator app.
Paper or an offline vault for backup codes. Working email and phone on the account.
Time for a test login once binding is done.
Bind and back up, in the right order
The rule is back up first, bind second: Open the security centre, choose authenticator, and copy the key before scanning anything.
Scan with the app and confirm it produces six-digit codes. Submit one code to test and confirm the binding works.
Write backup codes offline, stored separately from the key. When switching phones, import the key on the new device before signing out of the old one.
Fees, limits and processing times
Numbers change from time to time, always confirm on the official fee page before you commit size: Turn on Google Authenticator or a hardware key, then add withdrawal address whitelisting and an anti-phishing code to every email you receive.
Review the device list periodically, and use the global lock if you ever suspect a session is still active somewhere else. In-app chat is usually the fastest channel for account issues, and the help centre holds step-by-step articles for most problems.
For anything touching funds, open a ticket and keep the case number; never share passwords, codes or seed phrases with anyone claiming to be support. Official entry: type binance.com yourself or use your own bookmark, then check the padlock and the exact spelling before typing any password.
App install: search the publisher name "Binance" on App Store / Google Play, or pull the APK from the official download page rather than a third-party store.
The Binance-specific part
The Binance security centre supports several factors at once and stricter options such as hardware keys. After enabling, prune unused devices from the device list.
Frequently asked questions
I lost my phone.
Now what
Restore from backup codes or the stored key on a new device; without either you face the account recovery process.
SMS or app codes
Prefer the app. SMS can be intercepted or delayed, so keep it as backup.
Can I turn two-factor off
Yes, but it is ill-advised; you would leave only the password in place.

Use the app first and SMS as backup only. Anyone asking for your code is scamming you.
